of your medications or monitor you carefully for side effects.

Tell doctor if you have recently had severe vomiting or diarrhea and if you
have or have ever had heart, liver, or kidney disease; lupus; scleroderma;
or diabetes.

Tell your doctor if you plan to become pregnant or are breast-feeding.

If you are having surgery, including dental surgery, tell the doctor or
dentist that you are taking trandolapril.

You should know that diarrhea, vomiting, not drinking enough fluids, and
sweating a lot can cause a drop in blood pressure, which may cause
lightheadedness and fainting.
